EAST RUTHERFORD, N.J. - Michael J. Fox joined Coldplay on stage at a New Jersey concert where they paid tribute to "Back to the Future" by playing two songs the actor performed in the iconic 1985 movie.

Fox walked on stage at MetLife Stadium Sunday night just moments after the band showed a video of a fan asking them to play a tune from the "greatest movie of all time." He then played guitar on the early rock 'n' roll classics "Earth Angel" and "Johnny B. Goode."
